Background technique

Dental implant refers to a edentulous restoration method that supports and retains the upper dental restoration based on the lower structure implanted in the bone tissue. guide;

For example, a guide locator for implantation of oral implants disclosed by the authorized bulletin number CN207654260U, although it is convenient for medical personnel to accurately position and fix a cylinder similar to a tooth root, it reduces the damage to the adjacent blood vessels and nerves caused by the implanted tooth root. , while improving the work efficiency of medical staff;

However, when the existing guide locator is implanted, the guide locator is prone to relative displacement with the patient's tooth root, which reduces the accuracy of implant placement, and requires medical personnel to use lighting equipment to illuminate the patient's oral cavity from outside the patient's mouth. , resulting in poor surgical field of vision for medical staff, and the need for hand-held lighting equipment. After the implant is implanted, the lighting equipment is prone to forget to turn off. For this reason, we propose a guide locator for oral implant placement.

Example 1:

Please refer to Figures 1-4, an oral implant placement guide locator, including a gap locator 1 and a beak 2 fixed on the outside of the gap locator 1, the gap locator 1 is fixedly connected with a handle rod 3, the gap An auxiliary positioning mechanism is also provided on the outer side of the positioner 1 to provide an auxiliary force for fixing the gap positioner 1;

When the implant is implanted, the gap locator 1 is placed on the upper end of the patient's tooth root, and then the position of the handle bar 3 is adjusted to locate the handle bar 3. After the handle bar 3 is positioned, the gap is positioned by the auxiliary positioning mechanism. The device 1 is fixed to reduce the relative displacement between the handle rod 3 and the patient's tooth root;

1-2, the auxiliary positioning mechanism includes two clamping positioning plates 6 arranged on one side of the gap positioner 1, and an adjustment assembly for adjusting the positions of the two clamping positioning plates 6;

Here, the cross-section of the clamping and positioning plates 6 is arc-shaped, and the lower ends of the two clamping and positioning plates 6 are toward the end that is close to each other. The positional relationship of the two clamping and positioning plates 6 makes the two clamping and positioning plates 6 close to the sides of the teeth to fix the gap locator 1. At this time, the two clamping and positioning plates 6 form a U-shaped with an open lower end. , adapted to the shape of the teeth, can effectively prevent the clamping positioning plate 6 from falling off the teeth, and improve the stability;

Please refer to Fig. 3-4, the adjustment assembly includes a U-shaped frame 4 fixedly connected to the outside of the gap locator 1, the U-shaped frame 4 is provided with two guide grooves 11, and the two guide grooves 11 are slidably connected with The transmission plate 5, the two clamping and positioning plates 6 are respectively fixedly connected to one end of the two transmission plates 5 extending to the lower end of the U-shaped frame 4, and the U-shaped frame 4 is also provided with a transmission assembly to drive the transmission plate 5 to move;

The transmission assembly includes two transmission threaded rods 7 rotatably connected inside the U-shaped frame 4, the two transmission plates 5 are respectively threadedly connected with the two transmission threaded rods 7, and the ends of the two transmission threaded rods 7 close to the beak 2 both extend A rotating rod 8 is fixedly connected to the outer side of the U-shaped frame 4;

Here, the transmission plate 5 is provided with a clearance hole 12 and a threaded hole 13, the clearance hole 12 and the transmission threaded rod 7 are in clearance fit, and the threaded hole 13 and the transmission threaded rod 7 are threadedly connected. When the rotating rod 8 drives the transmission threaded rod 7 to rotate , because the transmission threaded rod 7 and the threaded hole 13 are threadedly connected, the transmission threaded rod 7 will drive one of the clamping positioning plates 6 to move through the threaded hole 13;
